This is a neat idea though it's usefulness is pretty small for anything beyond homebrew stuff. There aren't really any major GBA games with a lot of slowdown. Now the SNES. THAT system could use something like this.

Slow might be kind of cool for those who use the "slow motion" function on auto-controllers. Only this time it would be accurate instead of just pausing the game a bunch.

True Ian but I can think of one game that could benefit from this....Advanced Guardian Heroes. It would be nice to play the game without the ridiculous amount of slowdon. I mean Astro Boy came out some much better than AGH.

OCing the CPU won't work well with consoles since most games will use the clock speed to determine how fast time goes by. That means that unlike PC games they won't realize that the CPU is faster and not use the additional cycles as a "headroom", they will still assume that a second consists of 16777216 cycles and when they get 33554432 cycles they will think that two seconds have passed. Hackers have OCed GBAs (and even XBoxes, okay, not OCed but replaced the CPU with a faster one) before.

The device also speeds up the music and increases the sound pitch as well.

Hey Guys, thanks for the feedback.

Can anyone think of any other GBA games that experience slowdown? So far I've heard of Advance Guardian Heroes and Crazy Taxi.

Also I wanted to mention that we've done some extensive testing with this modification and have not witnessed any noticable problems such as shortened battery life, heat problems or damage to the system (Nintendo makes very tolerant hardware). We're planning to sell both a professional installation service for the GBAccelerator as well as a 'Do-It-Yourself' kit for those who like to do their own mods. We'll be providing a one year warranty on our installation (just like all of our professional modifications) but of course installing yourself will be at your own risk.

The ARM7 was designed for a 33MHz clock so any overheating would surprise me.
Are there any games that run at the proper speed even with a modified clock rate? I'm sure Crazy Taxi and AGH would run unplayably fast on an OCed ARM7...

Didn't Wing Commander have problems with slowdown? And that Star Wars: Flight of the Falcon game? Probably the heavy poly-pushing games would benefit the most from this, if they had slowdown problems. (Ozzy and Drix used polys as well, I think, I don't remember if anyone mentioned slowdown, though.)

Of course it wouldn't just compensate for the slowdown, it would speed up everything else, too.
